TO ALL WHOM IT MAY COHNCERN:

Ile it known that'I, W. F. HELLEN, of the city of Washington, and District of Columbia, have invented a nenv and useful Adjustable Skate-Sharpener; and I do hereby declare thefollowing to be an exact description thereof, reference being had to the accompanying drawings, and to the` letters of reference marked thereon, making a part of this specification, inwhich- Figure 1 represents a perspective View; and

' Figure 2, a eross-secti0n. v v

The nature of my invention consists inlth construction of the slotted guides B, as adjusted by the screw E and the set-screws D, all in combination with the adjustable file A. A representsv the fiat file, that may be made of any size or shape, the le fitting into corresponding shaped slots C of square guides or metallic plates, I3, the one side of file being held firmly iuthe slot and adjusted by set-'screws D passing through the top edge of oue'of the plates B, the other guide-plate B moving back or forward ou the le by means of the adjusting screw E, so as to open' the space between thevguide-plates B of suicient width to operate the file on anyr'sized skate, thebottom eilt-he skate being sharpened by the file, and the guide-plates B moving on each side of the runner of the'skate, the lplate in red lines showing hou' it is adjusted und operated by the adjustable screw E. i

I am nn'are of a file beingrivetedand permanently fixed between side-plates for sharpening a skate, but these I do not claim; but what I claim as my invention, and desire to secure by Letters Patent, is d The slotted guide-plate B, wit-h the adjustable screws D und set-screw E, combined with an adjustable file of any required size or shape, when constructed, arranged, and operated as herein described and for the purposes set forth.
